A new Request for Comments is now available in online RFC libraries. RFC 7637 Title: NVGRE: Network Virtualization Using Generic Routing Encapsulation Author: P. Garg, Ed., Y. Wang, Ed. Status: Informational Stream: Independent Date: September 2015 Mailbox: pankajg@microsoft.com, yushwang@microsoft.com Pages: 17 Characters: 40042 Updates/Obsoletes/SeeAlso: None I-D Tag: draft-sridharan-virtualization-nvgre-08.txt URL: https://www.rfc-editor.org/info/rfc7637 DOI: http://dx.doi.org/10.17487/RFC7637 This document describes the usage of the Generic Routing Encapsulation (GRE) header for Network Virtualization (NVGRE) in multi-tenant data centers. Network Virtualization decouples virtual networks and addresses from physical network infrastructure, providing isolation and concurrency between multiple virtual networks on the same physical network infrastructure. This document also introduces a Network Virtualization framework to illustrate the use cases, but the focus is on specifying the data-plane aspect of NVGRE.
